RB 00728 Gravity interpretation of the western Otway Basin between Cape Jaffa, SA, and Warrnambool, Victoria.

Author: Kendall, G.W.

From Bouguer anomaly maps of the western onshore portion of the Otway Basin, a residual gravity map has been constructed, from which the subsurface geological structure is interpreted to give good agreement with known geology. The area is one of complex gravity features in which a major increase of regional gravity towards the coast is interpreted as being from intra-basement sources, and in which several Bouguer anomalies are interpreted as intra-basement intrusions.
